The invention discloses an
modacrylic nylon cotton fabric continuous pad
dyeing method and a continuous pad
dyeing method thereof, and belongs to the technical field of fabric preparation. The method comprises the following steps: sequentially performing scouring and bleaching, singeing, mercerizing,
sizing,
dyeing, after-finishing tentering and preshrinking on the
modacrylic nylon cotton fabric to obtain a finished product, wherein the specific dyeing process is as follows: padding the shaped fabric in dye liquor at the speed of 50-60 m / min, then sequentially carrying out pre-
drying and
drying in three groups of
drying chambers, and sequentially carrying out baking, reduction
steaming, oxidation,
water washing, soaping,
water washing and drying on the dried fabric to obtain the dyed fabric. According to the continuous pad dyeing method, continuous pad dyeing treatment is conducted through a long vehicle, the production process is short, efficiency is high, the fabric has the advantages of being high in brightness, level dyeing degree, dry and wet
rubbing fastness,
fiber staining fastness and washing color fastness, good in hand feeling and small in
color difference, the production efficiency is greatly improved, and application and popularization of the continuous pad dyeing technology of the
modacrylic nylon cotton are promoted.
